Is Augmentin Safe in Pregnancy? Amoxiclav Checks
Published 2026-07-11 | By SafeMama Editorial Team | Editorial policy
Short answer
Augmentin can be used in pregnancy when a clinician prescribes it for a bacterial infection. It contains amoxicillin plus clavulanic acid, also called amoxicillin-clavulanate, amoxiclav, or co-amoxiclav. Do not self-start it. The decision depends on the infection, culture result when relevant, trimester, allergy history, dose label such as 625 mg or 1 g, side-effect risks, and whether there is any concern for leaking fluid or PPROM.
Use when prescribed for an infection
What is the safest way to think about this?
MotherToBaby says most studies have not found an increased chance of birth defects with first-trimester amoxicillin-clavulanate exposure, although combination-specific data are more limited than amoxicillin-only data. BUMPS says amoxicillin, co-amoxiclav and penicillin V can be taken in pregnancy if recommended by a doctor, and NHS says co-amoxiclav can usually be taken in pregnancy when a doctor thinks it is needed. NHS also lists diarrhea, nausea, vomiting and thrush as common side effects, with rare but serious reactions needing medical help. UKTIS says culture and sensitivity results should guide treatment where possible, and that co-amoxiclav should not be used for pre-labour premature rupture of membranes because of a possible newborn NEC concern. ACOG-linked UTI guidance also keeps culture results and resistance in the decision.

What is generally okay?
- Take Augmentin only if it was prescribed for your current infection. Do not use an old course because a search result says it is commonly used in pregnancy.
- For UTI symptoms, ask whether urine culture or sensitivity results support Augmentin. ACOG-linked guidance keeps culture results, resistance and targeted antibiotic choice in the decision.
- Check the active ingredients if the label says Augmentin 625 mg, Augmentin 1 g, amoxicillin-clavulanate, amoxiclav, co-amoxiclav, clavulanic acid, or clavulanate potassium.
- Ask what improvement to expect and when to call if fever, urinary pain, dental pain, sinus symptoms, chest symptoms, skin infection signs, or bite-wound symptoms do not improve.
- Tell your clinician about penicillin allergy, previous severe diarrhea, liver problems, jaundice with antibiotics, kidney disease, glandular fever, warfarin, methotrexate, breastfeeding plans, or recent antibiotic use.
What should you avoid or double-check?
- Avoid leftover Augmentin or antibiotics borrowed from someone else.
- Avoid using it for viral colds, flu, COVID symptoms, or any infection that has not been diagnosed.
- Avoid changing dose strength, splitting tablets, stopping early, or switching antibiotics without prescriber or pharmacist advice.
- Avoid treating leaking fluid, PPROM, contractions, fever, flank pain, jaundice, severe diarrhea, rash, breathing trouble, severe stomach or back pain, or worsening infection symptoms as routine side effects.

Frequently asked questions
Is Augmentin safe in pregnancy?
It can be used when a clinician recommends it for a bacterial infection. Do not self-start it or reuse leftovers because infection type, allergy history, culture results, trimester and dose strength matter.
What should I know about Augmentin in pregnancy?
The useful question is whether Augmentin matches the infection. Ask about the diagnosis, culture result, resistance risk, allergy history, dose strength, trimester and symptoms that should trigger a call.
Is Augmentin safe during pregnancy?
It may be appropriate when prescribed for a confirmed or strongly suspected bacterial infection. Ask what diagnosis is being treated and what follow-up is needed if symptoms do not improve.
Can I take Augmentin while pregnant?
Only if it was prescribed for you. Ask why Augmentin is the right choice, whether culture results support it, and what side effects should trigger a call.
Can you take Augmentin when pregnant?
Yes, in some cases, when a clinician chooses it for the infection. Do not start Augmentin from an old packet or from someone else's prescription.
Can pregnant women take Augmentin?
Some pregnant patients are prescribed Augmentin, but it should be based on the infection and the person taking it. Pregnancy does not make leftover antibiotics safe to reuse.
Is amoxicillin-clavulanate safe in pregnancy?
It may be prescribed when that antibiotic combination is the right match for the infection. The decision depends on infection type, allergy history, culture results, trimester and clinician judgment.
What is co-amoxiclav in pregnancy?
Co-amoxiclav is amoxicillin plus clavulanic acid. In many markets, Augmentin is a brand name for the same antibiotic combination.
Is co-amoxiclav the same as Augmentin?
Co-amoxiclav is another name for amoxicillin plus clavulanic acid. Brand names and doses vary by market, so check the active ingredients.
Is amoxiclav the same as Augmentin?
Amoxiclav is another label name for amoxicillin plus clavulanic acid. Ask a pharmacist to confirm the exact active ingredients and strength on your package.
Is Augmentin 625 mg safe in pregnancy?
Treat 625 mg as a dose-strength label, not a separate pregnancy-safety answer. The right strength and schedule depend on the infection, kidney function, culture results and prescriber plan.
Is Augmentin 1 g safe in pregnancy?
Do not switch between 625 mg, 1 g, tablet, liquid, or extended-release forms without a prescriber or pharmacist. The dose depends on the infection and your health history.
Is Augmentin safe in the first trimester?
MotherToBaby says most studies have not found an increased chance of birth defects with first-trimester amoxicillin-clavulanate exposure, but your clinician should still decide whether it is needed.
Is Augmentin safe in the second trimester?
It may be used when prescribed, but the infection and dose still matter. Ask what symptoms should improve and whether culture results could change the antibiotic.
Is Augmentin safe in the third trimester?
It may be used when prescribed, but timing and the reason matter. Tell your clinician urgently if you have leaking fluid, fever, contractions, or concern for pre-labour rupture of membranes.
Is Augmentin contraindicated in pregnancy?
Not as a blanket rule. It may be avoided in specific situations, including some PPROM-related care, allergy, prior antibiotic-related jaundice, certain liver or kidney issues, or when culture results point to a better option.
What does pregnancy category mean for Augmentin?
Older pregnancy categories are less helpful than an individualized risk-benefit discussion. Ask your clinician about the infection, alternatives, trimester, allergy history and source-specific cautions.
Is Augmentin stronger than amoxicillin?
It combines amoxicillin with clavulanic acid, which can help against some bacteria that resist amoxicillin alone. The choice depends on the infection.
Can Augmentin treat a UTI in pregnancy?
Sometimes. A clinician may choose it for certain UTIs, but urine culture results, local resistance, allergy history and symptom severity can change the plan. Ask whether the antibiotic should change when culture results return.
What does NHS say about co-amoxiclav in pregnancy?
NHS says co-amoxiclav can usually be taken in pregnancy when a doctor thinks it is needed. That still means you should use your own prescription and ask about the infection being treated.
What does BUMPS say about co-amoxiclav in pregnancy?
BUMPS says amoxicillin, co-amoxiclav and penicillin V can be taken in pregnancy if recommended by a doctor, and that treating infection correctly matters.
What side effects of co-amoxiclav matter during pregnancy?
NHS lists diarrhea, nausea, vomiting and thrush as common side effects. Call promptly for severe or bloody diarrhea, dehydration, rash, breathing symptoms, jaundice, severe stomach or back pain, or worsening infection symptoms.
Can I take Augmentin while breastfeeding?
NHS says co-amoxiclav can usually be taken while breastfeeding, but to check with a pharmacist or doctor first. Ask urgently if a baby has diarrhea, thrush, rash, poor feeding, unusual irritability or unusual sleepiness.
Can untreated infection be worse than antibiotics?
Sometimes yes. In pregnancy, untreated bacterial infections can matter, so antibiotic decisions should be made with a clinician.
